Medicinal use of olive leaves dates back to ancient Egypt and is referenced by Hippocrates and now in modern medical texts. Olive leaves contain powerful antioxidants and natural plant actives that are highly anti-microbial. Olive leaf is widely used around the world as a health tonic and all-purpose powerful antioxidant, to promote general health, and in the event of colds, flu or infection.
